Check the wires with an inductive timing light. Check for rhythmic flash. If any wires have a miss or multiple flashes, then it's either the cap, wire, or plug. Sometimes when spark plug leads are installed without dielectric grease they are difficult to remove & are damaged upon removal. I would trouble shoot first by inspecting the cap & rotor, then changing the wire, then changing the plug.
If the electrical system checks OK then investigate the injectors.

clean the distributer cap and rotor. for $20 you may just want to get a new cap and rotor. next you may want to pull the plugs and do a spark gap test on each cylinder to verify that your getting a descent spark.

It could be out of timing or you may need a new distributor cap and rotor
